Xa ukwakhiwa kwemigca yamanzi aphantsi komhlaba athembekileyo kwaye ahlala ixesha elide, ukukhetha uhlobo lombhobho olufanelekileyo lubalulekile.Imibhobho yentsimbi ye-SSAW, eyaziwa ngokuba yi-submerged arc welded steel pipes, idlala indima ebalulekileyo ekuqinisekiseni intembeko kunye nobomi benkonzo yeenkqubo zokuhanjiswa kwamanzi aphantsi komhlaba.Olu hlobo lombhobho lusetyenziswa kakhulu ngenxa yamandla ayo aphezulu, ukumelana nokugqwesa okugqwesileyo, kunye nokufakwa lula.Kule bhlog, siza kuphonononga iingenelo kunye nokusetyenziswa kwemibhobho yentsimbi edityanisiweyo ye-arc kwimigca yamanzi aphantsi komhlaba.
Imibhobho yentsimbi ye-SSAW yenziwa ngenkqubo ye-spiral ye-arc welding eshukumayo, ebandakanya ukusebenzisa iindlela ezikhethekileyo zokuwelda ukudibanisa imiphetho yeentsimbi zentsimbi ukwenza ubume be-cylindrical.Le nkqubo ivelisa amandla,intsimbi ejikelezayoimibhobhoezilungele izicelo eziphantsi komhlaba.Enye yeenzuzo eziphambili zombhobho wensimbi we-SSAW kukuxhathisa kwayo okuphezulu, okwenza ukuba ilungele ukuthuthwa kwamanzi kunye nezinye izinto eziphantsi komhlaba apho ukuvezwa komswakama kunye neemeko zomhlaba kungenakuphepha.
Ukongeza kwi-corrosion resistance, i-spiral submerged arc welded steel pipes ziyaziwa ngamandla abo aphezulu kunye nokuguquguquka.Ezi zakhiwo zivumela umbhobho ukuba umelane nemithwalo yangaphandle kunye nokutshintsha koxinzelelo ngaphandle kokuchaphazela ingqibelelo yayo yesakhiwo.Oku kubaluleke ngakumbi kwimigca yamanzi angaphantsi komhlaba, njengoko imibhobho inokuchaphazeleka ngamandla angaphandle afana nokuhamba komhlaba okanye imithwalo yezithuthi.Amandla endalo yombhobho wensimbi we-SSAW unceda ukunciphisa umngcipheko wokuvuza kunye nokugqabhuka, ukuqinisekisa ukunikezelwa kwamanzi okuthembekileyo, okuqhubekayo kubasebenzisi bokugqibela.
Ukongezelela, inkqubo ye-welding esetyenziswa ekuveliseni imibhobho yensimbi ye-SSAW iphumela ekugqityweni okugudileyo, okufanayo.Oku akugcini nje ukwandisa i-aesthetics yombhobho, kodwa kwakhona kunciphisa ukuchasana kwe-frictional, ngaloo ndlela kuphuculwe ukuhamba kwamanzi kumbhobho.Imibhobho yentsimbi ye-SSAW ngoko inceda ukunciphisa ukusetyenziswa kwamandla kunye neendleko zokusebenza ezinxulumene nokumpompa amanzi ngothungelwano olungaphantsi komhlaba.
Ukuguquguquka kombhobho wensimbi we-SSAW kwandisa ngakumbi ukuba kube lula ukufakela.Ubume obuguquguqukayo bombhobho buvumela ukuba uqhutywe ngokulula kwaye ubekwe kwiimeko ezahlukeneyo zomhlaba, okwenza kube lula kuzo zombini iinkqubo zokubonelela ngamanzi ezidolophini nasezilalini.Ukongezelela, iindlela zokujoyina ezisetyenziselwa ukufakela umbhobho wensimbi we-SSAW zinciphisa imfuno yezixhobo ezikhethekileyo kunye nomsebenzi, ngaloo ndlela ukunciphisa ixesha lokufakela kunye neendleko.
Isishwankathelo, ukusebenzisa i-spiral submerged arc welded steel pipe kwimigca yamanzi aphantsi komhlaba inika iingenelo ezininzi, ukusuka ekuxhathiseni ukonakala okuphezulu kunye namandla ukuze kube lula ukufakela kunye neemfuno zokugcinwa okuphantsi.Njengesisombululo esithembekileyo nesingabizi kakhulu, imibhobho yentsimbi edityanisiweyo ye-arc edityanisiweyo idlala indima ephambili ekuqinisekiseni ukusebenza kakuhle kunye nokuphila ixesha elide kweenkqubo zokuhambisa amanzi aphantsi komhlaba.Xa ukhetha imibhobho yemigca yamanzi aphantsi komhlaba, kubalulekile ukuqwalasela izibonelelo ezizodwa ezibonelelwa ngumbhobho wentsimbi odityanisiweyo we-arc wentsimbi.Ngokusebenza kwayo okungqiniweyo kunye nerekhodi yokuqina,umbhobho wentsimbi we-arc ojikelezayoihlala ilukhetho lokuqala lwezixhobo zamanzi kunye nabaphuhlisi beziseko ezingundoqo.
